John, so yeah if you're seeing 'edidfail', then your bug is 94994. I recommend subscribing to that one. I have some ideas on that one and am hopeful we can knock it out next week; there's been some really good successes the past couple weeks at solving some long standing resolution bugs, and I think we're on a roll. It would kick ass if we could eliminate all these major resolution issues for Gutsy!
Demosthenes, try sudo apt-get install xresprobe; that should get ddcprobe installed for you. For those of you on this bug's mail list, the website address is https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/3731 The past day I've been going through and looking at hundreds of resolution bugs. It is astounding how many of them on close look turn out to just be bug 27667 in one form or another. I think that bug fix by itself is going to go a long way towards remedying Ubuntu's reputation for poor resolution detection support. I hadn't expected we'd be able to close so many of these resolution bugs until Hardy! ** Description changed: I'm upgrade my system to ubuntu 5.10, after that, xorg can't load the correct resolution of the monitor ( 1024 x 768 ). I'ts only load 640x480. I've used dpkg-recunfigure xserver-xorg, and insert the correct values, but don't work. The system is a Samsung 753dfx and a gforce mx 200 32mb. [Update] A lot of people have reported this same bug. Symptoms include: - * Your hardware supports a variety of resolutions, but Ubuntu only runs in 640x480, 800x600, and/or 1024x768 + * Your hardware supports a variety of resolutions, but Ubuntu only runs in 640x480, 800x600, and/or 1024x768. If you have all three resolutions, but expect more, you are likely seeing bug 27667, bug 49827, or bug 94994. * In the "Monitor" section of /etc/X11/xorg.conf, your monitor is listed as "Generic Monitor", with HorizSync and VertRefresh rates that do not match your monitor - * `xresprobe <driver>` fails to work, or does not return accurate information for your hardware. (You can find your driver by looking in /etc/X11/xorg.conf for the line "Driver ..." It will be something like 'ati', 'nv', 'nvidia', etc. If you are using this on a laptop, run `xresprobe <driver> laptop`. + * `sudo xresprobe <driver>` fails to work, or does not return accurate information for your hardware. (You can find your driver by looking in /etc/X11/xorg.conf for the line "Driver ..." It will be something like 'ati', 'nv', 'nvidia', etc. If you are using this on a laptop, run `sudo xresprobe <driver> laptop`. Also run `sudo ddcprobe` - if you see "edidfail" then you are experiencing bug 94994. - The work-around for this bug is to edit /etc/X11/xorg.conf and replace + One work-around for this bug is to edit /etc/X11/xorg.conf and replace the rates with ones that match your monitor. The section should look something like this: Section "Monitor" Identifier "Generic Monitor" VendorName "SNY" ModelName "SDM-S91" Option "DPMS" HorizSync 28-80 # Important: Use horizontal frequency for your monitor VertRefresh 48-75 # Important: Use vertical frequency for your monitor EndSection Your monitor's documentation will tell you what the frequencies are. It's typically on a data sheet in the back of the book titled "Input Signal" or similar. If you don't have the printed manual, you can usually also find it on the manufacturer's website. Alternatively, you can try running `sudo dpkg-reconfigure xserver-xorg` and specifying the refresh rates through that interface, if you wish to avoid hand editing config files. Note that this will replace your xorg.conf file entirely. - The proper fix for this bug is to identify WHY xresprobe isn't working, - and for this we will need everyone's help. Here are some ideas on why - it may or may not work, that need testing: - - * Does it work with DVI monitors? - * Does it work with KVM switches? - * Does it work with DVI-to-VGA adapters? - * Does it work with HD monitors? - * Does it work with multi-headed systems? - * Does it work on non-x86 systems (AMD64, PPC64, et al)? - - If you are having resolution problems, you can help by running xresprobe - (see above) and if it fails, then try to think of anything a-typical - about your system, and report your findings in the comments of this bug. + If you're running Gutsy, then you can also try the Screen and Graphics + GUI admin tool, which lets you reconfigure your xorg.conf in a graphical + manner. ** Tags removed: metabug -- Xorg resolution falling back to 640x480 and/or 800x600 when h/v freqs incorrect https://bugs.launchpad.net/bugs/3731 You received this bug notification because you are a member of Kubuntu Team, which is a subscriber of a duplicate bug. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
